Hi,

this series based on a previous work from Chris adds support for
partial mapping.

Two preparatory patches are needed:

 - set the vm_pgoff when mapping frame buffer objects
 - do not fail when the exact address of a VM node is not the
   same as the starting address due to the offset.

Indeed I was receiving a negative offset at first.

Igt tests have been sent to the igt mailing list.
